スプレー缶の圧抜き構造Pressure release structure of spray can

本発明は、化粧品、塗料、又はプロパンガス等を圧縮充填しておいて噴出させるスプレー缶の圧抜き構造に関する。   The present invention relates to a pressure relief structure for a spray can that is compressed and filled with cosmetics, paint, propane gas, or the like.

従来から、化粧品等の流体をスプレー缶に充填して販売している。図５に、このスプレー缶の一例として、化粧品のスプレー缶１０１を示す。スプレー缶１０１は、化粧品（流体）１０２を圧縮して入れる密閉缶体１０３と、この化粧品１０２を外部へ導く噴出経路１０４と、この噴出経路１０４を閉鎖又は開放する開閉手段１０５とを備えている。噴出経路１０４は、図６に示すように、密閉缶体１０３内の化粧品１０２内に通じるパイプ１０６と、外部に通じる噴出口１０７と、パイプ１０６及び噴出口１０７を連結する連結経路１０８とを備えている。連結経路１０８は、パイプ１０６を支持するパイプ支持部材１０９の中空部１１０と、パイプ支持部材１０９に挿入された移動部材１１１の中空部１１２とから構成される。開閉手段１０５は、中空部１１０と中空部１１２との連結部を閉鎖するパッキン１１３と、移動部材１１１を押し下げてパッキン１１３による閉鎖を開放する押圧部材１１４とから構成されている。このスプレー缶１０１は、パッキン１１３によって噴出経路１０４を閉鎖して密閉する一方で、使用時には、図７に示すように、押圧部材１１４を指１１５で押し下げてパッキン１１３を変形させ、噴出経路１０４を開放して化粧品１０２を外部へ噴出させることができる。 Conventionally, cosmetics and other fluids are filled in spray cans and sold. FIG. 5 shows a cosmetic spray can 101 as an example of the spray can. The spray can 101 includes a sealed can body 103 into which cosmetics (fluid) 102 is compressed, a jetting path 104 that guides the cosmetics 102 to the outside, and an opening / closing means 105 that closes or opens the jetting path 104. . As shown in FIG. 6 , the ejection path 104 includes a pipe 106 that communicates with the cosmetic product 102 in the sealed can body 103, a spout 107 that communicates with the outside, and a connection path 108 that couples the pipe 106 and the spout 107. ing. The connection path 108 includes a hollow portion 110 of the pipe support member 109 that supports the pipe 106 and a hollow portion 112 of the moving member 111 inserted into the pipe support member 109. The opening / closing means 105 includes a packing 113 that closes the connecting portion between the hollow portion 110 and the hollow portion 112, and a pressing member 114 that pushes down the moving member 111 to open the closing by the packing 113. While the spray can 101 closes and seals the ejection path 104 with the packing 113, in use, as shown in FIG. 7 , as shown in FIG. 7 , the pressing member 114 is pushed down with a finger 115 to deform the packing 113, The cosmetic 102 can be ejected to the outside by opening.

このようなスプレー缶１０１は、廃棄する場合には、多少残っているガスの暴発を防止するために、押圧部材１１４を指１１５で押し下げて化粧品１０２を殆ど全て噴出させることにより、密閉缶体１０３内の圧力を抜いて外部圧力と略同じにしていた。しかし、このようにして圧力を抜くには時間がかかった。また、密閉缶体１０３に孔を開けることによって密閉缶体１０３内の圧力を抜くこともあった。しかし、この場合には、工具を使用して困難な作業を行う必要があり、専用装置を使用する場合にはコストが必要となった。   When such a spray can 101 is discarded, in order to prevent the remaining gas from exploding somewhat, the pressing member 114 is pushed down with a finger 115 to eject almost all of the cosmetic 102, thereby closing the sealed can 103. The internal pressure was released to make it almost the same as the external pressure. However, it took time to release the pressure in this way. Further, the pressure in the sealed can body 103 may be released by opening a hole in the sealed can body 103. However, in this case, it is necessary to perform a difficult operation using a tool, and a cost is required when using a dedicated device.

そこで、本発明者は、スプレー缶の圧抜き構造に関して、さらに鋭意研究を重ねた結果、本発明に至ったのである。すなわち、本発明は、使用済のスプレー缶を廃棄する際に、スプレー缶の内圧を、容易、迅速かつ安全に抜くようにすることを目的とする。   Therefore, the inventor of the present invention has made the present invention as a result of further earnest research on the pressure relief structure of the spray can. That is, an object of the present invention is to easily, quickly and safely release the internal pressure of the spray can when the used spray can is discarded.

本発明は、流体を圧縮して入れる密閉缶体と、該密閉缶体内の流体を外部へ導く噴出経路と、該噴出経路を閉鎖又は開放する開閉手段と、該噴出経路を開放した状態に維持する開放維持手段と、から成るスプレー缶の圧抜き構造であり、
前記噴出経路は、前記密閉缶体内に通じるパイプと、外部に通じる噴出口と、該パイプ及び該噴出口を連結する連結経路と、から構成され、
前記連結経路は、前記パイプを支持するパイプ支持部材の中空部と、該パイプ支持部材に挿入された移動部材の中空部と、から構成され、
前記開閉手段は、前記パイプ支持部材の中空部と前記移動部材の中空部との連結部を閉鎖するパッキンと、前記移動部材を押し下げてパッキンによる閉鎖を開放する押圧部材と、から構成され、

前記開放維持手段が、前記ガードに折り曲げ可能に設けられた折曲プレートから構成されており、
前記レバーを操作して前記押圧部材を押し下げた状態で、前記折曲プレートを折り曲げて該折曲プレートの下側で該押圧部材を係合させることによって、前記噴出経路を開放した状態に維持して前記密閉缶体内の圧力を外部へ抜くことを特徴としている。 The present invention provides a sealed can body that compresses fluid, an ejection path that guides the fluid in the sealed can body to the outside, open / close means that closes or opens the ejection path, and maintains the ejection path in an open state. A pressure relief structure of a spray can comprising:
The ejection path is composed of a pipe that communicates with the inside of the sealed can, an ejection opening that communicates with the outside, and a coupling path that connects the pipe and the ejection port.
The connection path includes a hollow portion of a pipe support member that supports the pipe, and a hollow portion of a moving member that is inserted into the pipe support member.
The opening / closing means is composed of a packing that closes a connecting portion between the hollow portion of the pipe support member and the hollow portion of the moving member, and a pressing member that pushes down the moving member to open the closing by the packing,
A guard is attached to the caulking projection of the sealed can so as to surround the pressing member, one end of the pressing member is connected to the guard, and a lever is provided at the other end of the pressing member,
The opening maintaining means is composed of a folding plate provided on the guard so as to be bent,

開放維持手段を備える本発明のスプレー缶の圧抜き構造によれば、噴出経路が開放した状態で維持できる。このため、スプレー缶を廃棄する際には、噴出経路が開放した状態に維持して放置するのみで圧力を抜くことができる。 According to the pressure relief structure of the spray can of the present invention provided with the opening maintaining means, the ejection path can be maintained in an open state. For this reason, when disposing of the spray can, the pressure can be released only by leaving the spray path in an open state.

しかも、この開放維持手段が、ガードに折り曲げ可能に設けられた折曲プレートから構成されているので、押圧部材を下へ移動させて折曲プレートを押圧部材側へ折り曲げるだけで、噴出経路を開放した状態に維持することができる。また、かしめ突起を有する従来の密閉缶体に適用できるので、ガード及び押圧部材を用意しさえすれば、従来の密閉缶体に対する圧抜き作業を行うことができる。In addition, since the opening maintaining means is composed of a folding plate provided on the guard so that it can be bent, the ejection path is opened simply by moving the pressing member downward and bending the bending plate to the pressing member side. Can be maintained. Moreover, since it can apply to the conventional sealed can body which has a crimping protrusion, if only a guard and a press member are prepared, the pressure release operation | work with respect to the conventional sealed can body can be performed.

まず、図１及び図２を参照しながら、従来の圧抜き構造を備えたスプレー缶について説明し、その後、図３及び図４を参照しながら、本願発明に係るスプレー缶の圧抜き構造について説明する。First, a spray can having a conventional pressure relief structure will be described with reference to FIGS. 1 and 2, and then a pressure relief structure for a spray can according to the present invention will be described with reference to FIGS. 3 and 4. To do.

図１及び図２に示すスプレー缶２００は、ヘアトリートメント等の化粧品（流体）を圧縮して入れる密閉缶体１４と、密閉缶体１４内の化粧品を外部へ導く噴出経路１６と、噴出経路１６を閉鎖又は開放する開閉手段１８と、噴出経路１６を開放した状態に維持する開放維持手段２０２とを備えている。開放維持手段２０２がスプレー缶の圧抜き構造として機能する。 A spray can 200 shown in FIG. 1 and FIG. 2 includes a sealed can body 14 into which cosmetics (fluid) such as a hair treatment is compressed, an ejection path 16 that guides the cosmetics in the sealed can body 14 to the outside, and an ejection path 16. Is provided with opening / closing means 18 for closing or opening and opening maintaining means 202 for maintaining the ejection path 16 in an open state. The opening maintaining means 202 functions as a pressure release structure for the spray can.

噴出経路１６は、密閉缶体１４内の化粧品内に通じるパイプ２２と、外部に通じる噴出口２４と、パイプ２２及び噴出口２４を連結する連結経路２６とを備えている。連結経路２６は、パイプ２２を支持するパイプ支持部材２８の中空部３０と、パイプ支持部材２８に挿入された移動部材３２の中空部３４とから構成される。開閉手段１８は、中空部３０と中空部３４との連結部を閉鎖するパッキン３６と、移動部材３２を押し下げてパッキン３６による閉鎖を開放する押圧部材３８とから構成されている。   The ejection path 16 includes a pipe 22 that communicates with the cosmetic in the sealed can body 14, a spout 24 that communicates with the outside, and a connection path 26 that connects the pipe 22 and the spout 24. The connection path 26 includes a hollow portion 30 of the pipe support member 28 that supports the pipe 22 and a hollow portion 34 of the moving member 32 inserted into the pipe support member 28. The opening / closing means 18 includes a packing 36 that closes the connecting portion between the hollow portion 30 and the hollow portion 34, and a pressing member 38 that pushes down the moving member 32 to open the closing by the packing 36.

開放維持手段２０２は、移動部材３２のまわりに回動可能な押圧部材３８に設けられた２個の凸部２０４と、密閉缶体１４に設けられた２個の爪部２０６とから構成されている。   The opening maintaining means 202 includes two convex portions 204 provided on the pressing member 38 that can rotate around the moving member 32, and two claw portions 206 provided on the sealed can body 14. Yes.

このスプレー缶２００は、化粧品用等として通常に使用する場合には、押圧部材３８を押圧して移動部材３２を下へ移動させることにより、移動部材３２に係合されているパッキン３６が変形し、中空部３０と中空部３４とが通じることとなる。中空部３０と中空部３４とが通じることにより、密閉缶体１４内の圧力によって、化粧品がパイプ２２から中空部３０及び３４を通って噴出口２４から噴出する。   When the spray can 200 is normally used for cosmetics or the like, the packing 36 engaged with the moving member 32 is deformed by pressing the pressing member 38 and moving the moving member 32 downward. The hollow portion 30 and the hollow portion 34 communicate with each other. By the communication between the hollow portion 30 and the hollow portion 34, the cosmetic is ejected from the jet port 24 through the hollow portions 30 and 34 from the pipe 22 due to the pressure in the sealed can body 14.

次に、スプレー缶２００が使用済となり、スプレー缶２００を廃棄する場合、押圧部材３８を９０°回動させ、押圧部材を押圧して移動部材３２を下へ移動させた状態で、図２（ａ）に示すように、凸部２０４を爪部２０６の下に係合させる。凸部２０４を爪部２０６の下に係合させることにより、図２（ｂ）に示すように、パッキン３６が変形して中空部３０と中空部３４とが通じる状態が維持される。中空部３０と中空部３４とが通じる状態が維持されることにより、押圧部材３８から手を離して放置しておいても、化粧品がパイプ２２から中空部３０及び３４を通って噴出口２４から噴出し続け、密閉缶体１４内の圧力が自動的に抜かれていく。   Next, when the spray can 200 becomes used and the spray can 200 is discarded, the pressing member 38 is rotated by 90 °, the pressing member is pressed, and the moving member 32 is moved downward in FIG. As shown to a), the convex part 204 is engaged under the nail | claw part 206. FIG. By engaging the convex portion 204 under the claw portion 206, the packing 36 is deformed and the state where the hollow portion 30 and the hollow portion 34 are communicated is maintained as shown in FIG. By maintaining the state in which the hollow portion 30 and the hollow portion 34 communicate with each other, the cosmetics can be passed from the pipe 22 through the hollow portions 30 and 34 from the spout 24 even when the pressing member 38 is left unattended. As the spray continues, the pressure in the sealed can 14 is automatically released.

このようにして化粧品を密閉缶体１４から抜くことにより、密閉缶体１４内の圧力が減少して略大気圧と同じになる。圧力が略大気圧と同じになった状態でスプレー缶２００を廃棄処分する。   By removing the cosmetic from the sealed can body 14 in this way, the pressure in the sealed can body 14 is reduced to be approximately the same as the atmospheric pressure. The spray can 200 is disposed of in a state where the pressure is substantially equal to the atmospheric pressure.

次に、本願発明に係るスプレー缶の圧抜き構造について説明する。Next, the pressure relief structure of the spray can according to the present invention will be described.
